Attractive Density

This project takes up the complexity of the requirements of contemporary life with respect to content and translates them into a characteristic morphology. Building housing also means building the city. On Breitenfurter Straße, a district conceived from the very beginning as integrative and inclusive is to be created, with the aim of bringing the individual human scale into harmony with urban density in an exemplary way.
Buildings of various heights and depths stand on an artificial mountain. The car park, basement rooms, storage, technology, and rubbish vanish beneath it. Above, a sequence of public squares, passageways, and distance and proximity develops on different levels. With no cars. Additional infrastructure that supplements the housing is located here. Character and intimacy arise within the large scale. The differentiated, interconnected district, which can be traversed on foot in multiple directions, is also inviting for users who do not live in the immediate area due to its density and vibrancy. There are no front or rear sides: the surrounding neighbourhoods are each offered a corresponding counterpart and accessibility. The diversity of the housing takes into account the needs of a pluralistic society. High housing satisfaction is the basis for all sustainability.

The inn and upscale restaurant Steirereck am Pogusch in the Austrian Alps brings together a down-to-earth quality, haute cuisine, high-tech work processes, sustainable agriculture, and a luxury hotel business under one roof. The supra-regionally well-known inn has been expanded on a large scale, but the changes remain largely invisible in the landscape. The project consists of existing buildings such as the stone house and the wooden house, which have been refurbished and elevated as well as expanded. These extensipns, namely the Salettl, the bar kitchen, the kitchen garden (a warm greenhouse) and a large glass house (cold greenhouse) are partly buried due to the hillside location. Through various calculated interventions, existing buildings and extensions now form a village ensemble at the scale of a rural development. PPAG also designed numerous details, such as organomorphic door handles, 3D-printed washbasins and spatially effective vertical wooden blinds, all of which bestow the project with the character of a cutting-edge, total work of art – and transport visitors to an unusual mountain world.

Glass houses
Glass houses at this altitude of over 1,050 m above sea level represent a special challenge. A tremendous drive for research, a small amount of crop cultivation and, last but not least, innovative and unconventional guest accommodations are the main focuses of the greenhouses. Off the glass houses, one is cold, the other warm and both have different tasks to fulfill: the large one, which is the  cold greenhouse (minimum temperature close to freezing point) is used for year-round plant cultivation. There are also unconventional overnight accommodations, for unconventional guests. A matching special bathing area is located beneath it. Connected to it is the warm greenhouse (approx. 22 °c), which supplies the kitchen with fresh herbs and spices and offers an intimate backstage area where new ideas can be cooked up. Both glass houses are connected to the kitchens located below via atria and enhance them with direct daylight. This large hidden world in the background, which contributes to the well-being of the guest, hardly appears in postcard images. But under the sward there are well-lit workplaces with an elevated spatial quality.

Stone house and wooden house
The pre-existing buildings – parts of the kitchen, the stone house from the 17th century and the wooden house – have been properly renovated with respect of the beauty of the old structures. The useful remained, however widely refurbished. The topography was altered as little as possible despite major construction work. The excavation was returned into the surrounding landscape. The positioning of the new buildings in relation to the pre-existing structure and the pathways that unfold in between express the essence of vernacular construction. The transitions between the zones are harmonious and self-evident, despite the radical nature of what has been newly built. Ultimately, the overall effect is effortlessely normal. Every element was injected with renewed life energy, all the while preserved from unnecessary bluster.

Bar kitchen
The bar and fire kitchen with a large grill is the part of the kitchen that is visible for the guest. Depending on the daytime, it is light and transparent, or atmospheric and dark against the background of the grill: a strong space in the heart of the house. The wooden elements used here – lightweight but able to support heavy loads –are a kielsteg ceiling. When installed in different directions, the trim cuts that would typically be concealed when employed the conventional way, are made visible. The thin, curved plywood panels that connect the upper and lower braces are repurposed as lighting for the guest area.

Salettl
The new Salettl, or gazebo, together with the existing stone house and wooden house, form differentiated dining rooms that can serve different concept of hospitality and atmosphere. In contrast to the pre-existing buildings, the Salettl is open and transparent, with a view of the surrounding nature. Spatial comfort is provided by flexible, changeable wooden slat curtains. A large number of different spatial arrangements can be set up in a simple and quick manner.

The Steirereck restaurant in Vienna has been one of the top gastronomic leaders in Austria for many decades and has been ranked one of the World’s 50 Best Restaurants for over than 10 years. In addition to the gastronomic concepts contemporary orientation, special attention is always paid to the sustainability of one’s own activities. With the renovation and extension project of the Steirereck am Pogusch, Heinz and Birgit Reitbauer want to show how innovative a gastronomic business can be.

The Pogusch is located at an elevation of 1,059 m above sea level: a high alpine pass in Upper Styria that connects the municipalities of Turnau and Sankt Lorenzen in the Mürz Valley. At the top of the pass, the Steirereck am Pogusch inn can be found with its main and ancillary buildings. Facing the “Bründl-Wanderweg” there is already an old building consisting of an inn, accommodation buildings and a building used for farming purposes.

After decades and generations, the agricultural work deeply linked to the restaurant and the mindful way of life that stemmed from the institution was to be manifested, tangible and visible for the operators themselves and for the guests. The challenge was to reconcile a situation characterized by the experience of nature with a highly demanding, contemporary catering business and to orchestrate a harmonious holistic solution for the future. The new gets to be visible, demonstrating the perspective of life in the 21st century away from the city, nonetheless linked to the know-how of the 21st century.

The pre-existing components – the kitchen, the accommodations, the stone house, the wooden house and the agriculture – were complemented by new relevant ones by PPAG – the kitchen extension, the salettl, the warm and the cold glass houses, the special employee and guest accommodations, including the expansion of visible and invisible infrastructure.

Affordable living in a prime location
78 residential units and 2 commercial units

Apartments starting at € 6.50/m² net cold rent have been built in a central location near Potsdamer Platz. The building is divided into two components with an “L-shape”, both have their own development core. A corner formation on the street side serves as an urban forecourt and allows encounters to the public space, while the planted inner courtyard offers a place of retreat.
The forward and backward leaping of the façade creates a strong verticality, while the staggered sequence of large balconies, on the other hand, seems to break through the horizontal of the regular floors.
